4385-5. Using the driving support systems
■ECB (Electronically Con-
trolled Brake System)
The electronically controlled sys -
tem generates braking force corre -
sponding to the brake operation
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv -
ing on a slippery road surface
■Brake assist
Generates an increased level of
braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces.
■VSC+ (Vehicle Stability Con -
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil -
ity when swerving on slippery road
surfaces by controlling steering per -
formance.
■Trailer Sway Control
Helps the driver t o control trailer
sway by selectively applying brake
pressure for individual wheels and
reducing driving torque when trailer
sway is detected.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin -
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent t he vehicle from
drifting to the outer side by perform -
ing inner wheel brake control when
attempting to acc elerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Po wer Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel
Driving assist systems
To keep driving safety and per -
formance, the following sys -
tems operate aut omatically in
response to various driving sit -
uations. Be aware, however,
that these sys tems are supple-
mentary and should not be
relied upon too heavily when
operating the vehicle.

Driving
■E-Four (Electronic On-Demand
AWD system)
Automatically switches from front
wheel drive to all-wheel drive
(AWD) according to the driving con -
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, start ing off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.
■Emergency brake signal
When the brakes are applied sud -
denly, the emergency flashers
automatically flash to alert the vehi -
cle behind.
■The Secondary Collision
Brake (if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the v ehicle speed and
help reduce the possibility of further
damage due to a secondary colli -
sion.
■When the TRC/VSC/ABS/Trailer Sway Control syst ems are operat-
ing
The slip indicator light will flash while the TRC/VSC/ABS/Traile r Sway Control
systems are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or snow, the TRC system may reduce
power from the hyb rid system to the
wheels.

4606-1. Using the air conditioning system and defogger
If the Remote Air Conditioning Sys-
tem is used while the AC charging
cable is connected to the vehicle,
electricity from an external power
source can be used minimizing the
drop in charge of the hybrid battery
(traction battery).
Charging will be co nducted automati-
cally after the Remo te Air Conditioning
System is stopped.
Check the temperature setting of
the air conditioning system.
( →P.452)
The Remote Air Conditioning System
will operate in accordance with the tem -
perature settings of the air conditioning
system.
Press and hold “A/C” on the wire -
less remote control to operate the
Remote Air Conditioning System.
The system can be s topped by press-
ing “A/C” twice.

The system will automa tically shut off under the following conditions:
●About 20 minutes have passed since operation began
●Any one of the operating conditions is not met
The system may also shut off if the
charge level of the hybrid battery (trac -
tion battery) drops to low.
■Conditions affecting operation
The system may not s tart in the follow-
ing situations:
●The charge level of t he hybrid battery
(traction battery) is low

low
●When the hybrid syst em is cool (for
example, after being left for a long time in low temperatures)
■Windshield defogger
When defogging the windshield using
the Remote Air Conditioning System, defogging may be insufficient due to the
power being restricted more than during
normal air conditioning operation. Also, the outside of the windshield may fog up
due to the outside temperature, humidity
or air conditioning set temperature.
■Using the heater via the Remote Air Conditioning System
●When the outside te mperature is low, heating may feel insufficient due to
restricted operation of the air condi -
tioning.
●When the outside heat exchanger
becomes frosted ov er, heating perfor- mance may decline due to automati -
cally switchi ng to the frost removal
operation. ( →P.452)
